[Bug report] Compiling & rendering too too too much slower than VitePress

[lslzl3000]

Description

Try to build with 1000 .md files
Vuepress takes more than 10min to compile and render, in both vite-bundler and webpack-bundler

Meanwhile, VitePress@1.0.0-alpha.4 only takes 30s

The core part of build-bundler - Vite is the same, so the problem may be how VuePress processes or organises .md and .vue. What is the difference between VitePress and VuePress during compiling & rendering?

Used Package Manager

npm

@meteorlxy I have created a simple repo to test VitePress and VuePress
https://github.com/lslzl3000/vuepressVSvitepress

It has about 1000 .md files, just simple doc generated from babylon.js
you can try build with VitePress and VuePress

1. You will see how much longer the VuePress will take
   In my Macbook Pro 2022 with M2, VuePress: 13mins+ vs VitePress：60-70s

2. VuePress also use much much more memory than VitePress
   It has to build with NODE_OPTIONS=--max_old_space_size=20480, otherwise node process will exit by JavaScript heap out of memory

If build with full VuePress theme and other plugins, it will take more time
